Title: Balance type signal amplifying circuit
Inventor: OOTA KUNIKAZU
IPC: G11C11/4091
Filed: 1980-03-31
Abstract: PURPOSE:To realize the operation of a balance type signal amplifying circuit by compensating the asymmetry of the capacity of bits, occurring on bit lines, to the symmetry of the element parameter of a sense circuit. CONSTITUTION:Firstly, when phi3 is at the high level, transistor (TR) Q11 is cut off during the operation of transfer gates Q7 and Q8, and an FF circuit is in operation by TRs Q2 and Q4. At this time, the ratio of beta2 and beta4 of those TRs is regarded as the ratio of bit capacities CB and C'B. In this case, however, mutual conductance gm of Q7 and Q8 is increased either by increasing betas of Q7 and Q8 or by holding phi3 very high. Next, as phi3 drops, signal amplification is performed only inside of FF operating by Q2 and Q4 and the unbalance between bit capacities CB and C'B is excluded by Q7 and Q8, so that balanced type FF will be preferable. For this purpose, beta11 and beta12 are so set that beta2+beta11=beta12+beta4 because Q13 turns on. Here, B is a common-emitter amplification factor and phi is a gate applied voltage.

Abstract: PROBLEM TO BE SOLVED: To obtain a portable vegetable and fruit maturity degree meter by allowing a collision part to collide with vegetables and fruits at a predetermined speed in a gun part and measuring the impulse waveform propagating along the surfaces of vegetables and fruits by a microphone. SOLUTION: A collision part 20 is allowed to collide with vegetables and fruits at a predetermined speed in a gun part 10 and the impulses propagating along the surfaces of vegetables and fruits by this collision are measured by a first microphone 30. A second microphone 31 is arranged so as to be separated from the first microphone 30 by a predetermined distance. An operational processing part 40 calculates the time lag between the impulse waveforms measured by the first and second microphones 30, 31 and a maturity degree judging part 50 compares this time lag with a reference propagation speed to judge whether vegetables and fruits come to maturity.  Since collision is applied to the surfaces of vegetables and fruits by using a gun type striking device, the measurement of a maturity degree can be simply performed as compared with a pendulum system and an apparatus can be made portable and, for example, the inspection of the maturity degree of vegetables and fruits before harvesting in a farm becomes convenient.

Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To obtain a provide a plasma display panel capable of suppressing metal dendrite, and to provide, manufacturing method and a driving method therefor. SOLUTION: A driving signal having the period when thick X-electrodes 6 become negative electrodes to thin Y-electrodes 7 equal to or longer than the period when the X-electrodes 6 become positive electrodes to the Y- electrodes 7 even in any sub-field period is applied to plural electrode pairs 8. Thus, since a 1st electrode wider in width acts as a negative electrode, metal dendrite can be suppressed. Moreover, in a 2nd period, it is possible to make the 1st electrode act as a negative electrode by aggressively applying to the 2nd electrode a voltage that makes the 1st electrode negative to the 2nd electrode.
